There's this cute little "climate change art group" called The Canary Project, which in turn is working on something called Green Patriot Posters, which looks to me like kids marketing climate change awareness in various ways.

The cute custom sneaks are the work of students at McCormack Middle School in MA, which were encouraged to express their knowledge of their carbon footprints on a pair each. The sneakers now appear in associated billboards along with the tagline: "The Kids at McCormack School know their CARBON FOOTPRINT. What about YOU?"

Casey writes, "It's got to be for something, but I'm not sure what it is..." Well thanks for the detailed information, Casey. We really appreciate it. But, yes, it's definitely for something but we know not what it is. Anyone care to shed some insight on why men and women are walking around New York today in swimwear?

Is it related to that similarly-themed promotion that had similarly-dressed men and woman wandering the streets of New York on Friday?

Probably one of the scariest things about human trafficking is that it's kinda like objectification brought to the lowest common denominator: you're not just eyeballing someone like a slab of meat; you're actually treating the person like an item on which you can impose your will.

Bringing this idea to stark relief, the German arm of Amnesty International celebrated the 60th anniversary of human rights in 2008 with "Frau im Koffer" ("Woman in Suitcase"), a guerrilla effort where a live contortionist was squeezed into a transparent suitcase and tossed onto a conveyor belt in baggage claim.

At Piccadilly Circus in London, McDonald's has a dynamic billboard that stimulates both engagement and viral behaviour.

Playing on the irresistible human desire to pretend to interact with stuff that isn't really there, the billboard randomly flashes things like umbrellas, bouncing soccer balls, dumbbells and thought bubbles -- all waiting for some eager pedestrian to position his head and/or arms in just the right spot so some content-starved intrigue-seeker can snap a shot for mom and dad at home.

Half of Adrants is Asian, which means we were irreparably traumatized by karaoke from an early age. But there's a contagious warmth to this effort by T-Mobile -- which can only be described as the Ultimate Karaoke Gangbang.

The mobile/communications firm projected the lyrics to the Beatles' Hey Jude over a billboard, then passed mics out to people on Trafalgar Square. It's neat to watch the faces: people look earnest, but uncertain, and over time they just kinda lose themselves in the na-na-nas and the feel-good Hey Jude-in'.

Samsung is doing something weird in Austria. And it has to do with its LED TVs and the online game Spore. They've taken to the streets with the Spore creature posing with people and leading them in a little dance.
